WATER. TANK FOR concamn-mhne maonmns.

Application filed November 14, 1921. Serial No. 514,549.

T all whom it may concern.

Be it known that I, G-EBHARD JAEGER, a

citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Water Tanks,

for Concrete-Mixing Machines, of which the following is a specification.

The object of this invention is to provide for a concrete mixing machine an improved water tank from which a definite and predetermined portion of water may be re moved for mixing with the other materials in the mixer, said tank having means con nected therewith for automatically replenishing the tank with water to a normal level whether the portion withdrawn for the mixer was large or small. Other objects will appear from the following disclosure.

The invention is embodied in the example herein shown and described, the features of novelty being finally claimed.

In the accompanying drawings Figure 1 is a side elevation of as much as is necessary of a concrete mixing machine showing my invention applied thereto.

Fig. 2 is a central section of the tank in its upright position.

Fig. 3 is a horizontal section on the line III-III Fig. 1.

In the views 5 designates the mixing drum which has a single opening 5 for supply and discharge and is mounted to rotate and oscillate in a suitable frame 6. Supported upon the frame above the'mixing drum is th swinging water tank 7 One of the supporting shafts 8 of said tank is made hollow and extended to the interior of adjustable on the stem by means of a set screw 11'. The supply of water is obtained through a flexible hose 12 spiraled around the hollow shaft and connected with said shaft in fixed relation thereto so that the tank can be oscillated and the necessity of providing bushings or stufling boxes avoided. The outer end or portion of the shaft 8 is made solid to close the end of the tubular portion and is provided with a hand lever- 13 for swinging the tank. The supporting'frame is provlded with a bar 14 having thereon an adjustable stop 14 to limit the throw of the lever 13 in the tankdischarging movement of the tank and therefore the quantity of water to be discharged into the mixing drum.

Toinsure the unseating of thev valve in the event it sticks after a discharge the stem thereof is extended beyond the tank in position to be actuated by a lever 15 pivoted at 15 on the tank, said lever being held in proper position to be actuated by the upper end of a bar 16 fixed on the main frame when the tank is swun anti-clock- Wise (see Fig. 1) to depress t c said stem 1 and unseat the valve. Whenever the valve has been thus unseated the tank is, of course,

iron 6 and interposed between the watertank and the mixer drum is achute 17 havmg a discharge mouth 17, said chute adapted to direct the water poured from the tank into the drum. Fig. 1 illustrates the position of the opening of the mixing drum 5 in its charging position. 1

The water supply pipe can be provided with a flexible extension 18 having a valve nozzle 19 for making up a deficiency of water in the drum in any particular instance where it appears the regular operation of the tank as first set for the operation has not supplied the needed quantity.

The forms of the parts can be changed without departing from the gist of the in vention as claimed.

What I claim is:

1. The combination with a mixing drum, of means for supplying water thereto including a tank, means for swinging the same to discharging and charging position and means carried by the tank for automatioally supplying and controlling the supply of water to said tank tion.

2. The combination with a mixing drum, of means for supplying water thereto including a tank, means for swinging the same to discharging and chargin position, adjustable means for limiting t e swin- 'ng of said tank to discharging position an means in the charging posicarried by the tank for automatically supplying and controlling the supply of water to said tank in the charging position.

3. The combination with a mixing drum, of means for supplying water thereto including a swinging tank having a hollow shaft, a coiled pipe connected with said shaft for supplying water to the tank, means for swinging the tank to discharging and charging position and means carried by the tank for automatically supplying and controlling the supply of water to said tank in the charging position.

4. The combination With a mixing drum, of means for supplying water thereto including a tank, means for swinging the same to discharging and charging position, a valve and float carried by said tank for controlling the supply thereof and means for automatically controlling the supply of water to said tank in the charging position and means actuated by the swinging of the tank in a direction opposed to dis-charging position for unseating the valve in said tank.

5. The combination with a mixing drum, of means for supplying water thereto including a tank, means for swinging the tank I and means for limiting the swing of the tank to limit the discharge therefrom.

6. The combination with a mixing drum, of means for supplying water thereto including a tank, means for swinging the tank from charging to discharging position, means carried by the tank for automatically supplying and controlling the supply of water to said tank in the charging position and adjustable means for limiting the swing of the tank to limit the discharge therefrom.
